Toilets are typically flushed with greywater, which is the leftover wastewater from showers, baths, and clothes washers. This greywater contains contaminants that can contaminate groundwater supplies if not treated properly. Greywater treatment systems give you an easy way to treat greywater onsite before entering the sewer system or seeping into your local groundwater supply. These systems solve many problems by reducing pollution of surface waters and protecting public health.
They Help With Water Conservation
Grey water treatment systems can help you save money on your water bill. The average family of four wastes more than 400 gallons of water each day from flushing toilets, washing dishes and clothes and watering plants. A greywater system can reduce this waste by as much as 50 percent.
They Protect Your Local Groundwater supply
These water treatment systems protect groundwater supplies by preventing greywater from entering the soil and contaminating groundwater. All untreated greywater contains pollutants that can harm aquatic life and contaminate drinking water supplies if left untreated.
They Keep Our Waters Clean
Every year, billions of gallons of raw sewage are discharged into our waterways because storm drains and wastewater Treatment Plants (WWTP) cannot handle the excess flow. When greywater is used to irrigate landscaping, it helps free up capacity at the WWTP and reduces the amount of raw sewage that needs to be treated.
They’re Good for the Environment
Greywater reuse saves water and energy, which reduces greenhouse gas emissions from power plants. Greywater systems are also beneficial because they use less potable water for irrigation, which means there is more available for human consumption in times of drought. It also means there is more available in times of emergencies. In 2007 alone, California used nearly one trillion gallons of fresh drinking water on landscape irrigation. If just a quarter of this were saved by greywater recycling instead, over 300 million people could have had enough fresh drinking water every year since then! Greywater recycling helps our environment too because these systems reuse soiled wastewater.
They Help Preserve Our Valuable Resources
These systems can help preserve our valuable resources by reducing wastewater discharge into rivers, lakes, and oceans. According to EPA estimates, if just half of the American homes installed greywater systems, we could save nearly 900 billion gallons of fresh drinking water each year. Greywater systems also help reduce the amount of wastewater going into treatment plants, which means less energy is required for pumping and treating it.
To conclude, greywater treatment systems are becoming more popular as people become more aware of the benefits. These systems recycle household wastewater, which is then used for irrigation or other purposes.
